COMPOSITION OF MATTER FOR REPAIR OF PNEUMATIC TIRES.

No Drawing.

Specification of Letters Patent. Application filed August 19, 1909. Serial No.

Patented June 14, 1910.

To all whom it may concern:

Be it known that I, JOHN H. LEWIS, a citi zen of the United States, residing at Joplin, in the county of Jasper and State of Missouri, have discovered a new and useful composition of matter to be used for the treatment of any and all kinds of pneumatic tires to prevent the escape of the air in case they are punctured, of which the following is a specification.

My composition consists of the following ingredients, combined in the proportions stated, viz

Ribbon glue 38 pounds Water 1% gallons Molasses -1 gallon 1 pint Linseed oil 5 pints Dissolve the glue in the water in a steam jacket kettle until the glue is thoroughly dissolved and the water evaporates, then add the molasses and boil one hour, then add the linseed oil and continue boiling under a steam pressure of 80 to 100 pounds until a thick dark jelly compound is obtained, then remove from the kettle and cool. By the union of this compound in this manner we obtain the first chemical change.

To prepare the tire for treatment remove the valve stem and wash out the inner tube with gasolene to remove the soapstone and other foreign substances.

Weigh out the amount of compound necessary for the treatment of the tire and remelt in the steam jacket kettle and add the folloving heat resisting agents, which consist o Chrome alum 5 oz. 100 grains Bichromate potash 4 330 Water suflicient to make twenty-five ounces.

To one pound of the compound add onehalf ounce of the above, previously dissolved in hot water and stir; when thoroughly mixed transfer to a pump and force into the inner tube while hot through the valve stem 1gperim'g'; distribute equally in the tube by an stem and inflate with air, then place on a revolving drum and keep in motion 4 or 5 hours to throw the compound to thetread of the tire and to cool it. By combining the heat resisting agents in this manner we get the second chemical change.

By the treatment of tires with'this compound they do not collapse and become useless for the reason that as soon as'the tireis punctured the compound reunites and prevents the escape of the air.

I claim:

1. The'hereinbefore described composition of matter consistin of ribbon glue, water, molasses, linseed oil chrome alum, and bichromate potash, substantially as described and for the purpose specified.

2. The herein-described composition of matter for the treatment of pneumatic tires to prevent the escape of air when punctured consisting of ribbon glue 38 pounds, water 1% gallons, molasses 1 gallon and 1 pint, linseed oil 5 pints, chrome alum 5 oz. 100 gr., bichromate potash 4 oz. 330 gr., water suflicient to make 25 ounces, substantially as described.
